The baseline refers to a starting point or standard against which future measurements or progress can be compared. It is often used in various fields, such as statistics, project management, and sports, to establish a reference point for evaluating performance or making decisions. In essence, the baseline serves as a benchmark or foundation for tracking and analyzing changes or improvements over time. It can also refer to the lowest level or minimum requirement that must be met before any further action can be taken. In short, the baseline is a crucial reference point that helps to measure progress and set goals in various contexts.
